Missing 3 supported languages of translation on WooCommerce's Pinterest Plug-in product webpage

[JohnnyCYu]

Describe the bug:

WooCommerce's Pinterest Plug-in product page webpage offers several supported languages for localization, but only Spanish and French pages are fully translated. The other languages are either partially translated or not been translated at all. (E.g. Brazilian, German, and Italian). Here is a sample webpage URL to Italian - https://woocommerce.com/it-it/products/pinterest-for-woocommerce/

Steps to reproduce:

1. Log on to product webpage
2. Select the national flags icon to choose the language
3. Review the texts and translation of this webpage under different languages

Expected behavior:

All webpages for the listed languages should be fully translated

Actual behavior:

3 webpages of the listed languages are not fully translated (E.g. Brazilian, German, and Italian)
